UNTTE STTES PATENT YARN CLEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 390,326, dated October2, 1888.

Serial No. ?,906. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY F. \VEST, a eitizen of the United States,residing at Gloucester Jity, in the county of Camden and State of NewJersey, have invented certain new and useful Improvements in aYarn'Gleaning Device, of which the following is a specification.

My invention has relation to certain novel features of improvement inthe construction of a device for cleaning yarn or other fibrous materialof the type forming the subject-mat ter of an application for LettersPatent filed by me on the 13th day of September, 1887, and seriallynumbered 249,543.

Theprincipal object of my present invention is to provide a deviceconsisting of two longitudinal bars each provided with a series ofknives disposed at an angle,and with supporting-seats and L-shapeddepending arms at right angles to said bars, the device beingconstructed so that it may be quickly set by hand for the performance ofits functions of cleaning or removing mote, fuzz, or small particlesfrom fibrous material in its passage between the knives of the device.

The nature of my invention will be more particularly understood taken inconnection with the accompanying drawings, wherein I have shown the samein a form found practically efficient, and in which Figure 1 is aperspective view of my improved cleaning device, and Fig. 2 is a sideelevation, partly in section, of so much of a spoolingmachine as willserve to illustrate the application of my improved cleaning devicethereto.

Referring to the drawings for a further description of the invention, Aand A are two rectangular shaped longitudinal bars each having dependingL-shaped arms a and a. In the upper portions of these arms are formedoblong slots a and a, for a purpose to be presently more particularlydescribed. (last with or otherwise secured centrally to the longitudinalbars A and A are right-angular supporting-seats B and B, having two ormore slots, 2) and 1), formed in the bottom thereof,through whichbroad-headed screws 0 and c are inserted for holding the bars with theirknives (to be presently more particularly described) in proper positionfor the cleaning of the fibrous material in its passage between them,

as fully shown in Fig. l. The longitudinal bars A and A have formedintegral therewith knives a and a, which are arranged in series at anyangle to the horizontal and vertical planes of the bars, and the sidesof which knives are beveled off or taper slightly from the longitudinalbars to the outer free extremities thereof, while the edges are eitherbeveled off or square.

D and D are horizontal rods threaded for a portion of their length fromboth extremities, on which nuts d (l and d d" are secured for retainingsaid rods in position vertically in the respective slots a and a" of thedepending arms a and a at each extremity of the longitudinal bars A andA. This arrangement of the rods D and D, forming guides for the yarn orother fibrous material in its passage between the two series of knivesof the device, affords simple and effective means whereby it is renderedpossible to utilize the entire cleaning-surfaces of the two series ofknives before there will be any occasion to remove the same forsharpening and grinding.

Vhen, however, it is found necessary to remove the knives for sharpeningand grinding, the operation may be readily conducted and the lower endextremities of the L-shaped depending arms a and a will be ground offuni formly with the knives, in order that when they are replaced thelower extremities ofthe L-shaped depending arms will serve to insureabsolute certainty of position for the knives, which may be quickly setby hand by simply placing the device on the supportingbracket,(shown,for instanee,in Fig. 2,) and then bringing the respectiveL-shaped depending arms of the bars A and A snugly up against eachother, which position, for certainty of action in the cleaning of thematerial ll] its passage between the knives of the device, will be foundclearly illustrated in Fig. 1 of the drawings.

E is a slightly-curved bracket Lil-shaped at one extremity, havingformed integral there with two rectangular-shaped seats, e,on which theright-angular supportingseats Band B, formed with the longitudinal barsA and A, are mounted and held to place thereon by means of screws 0,fitted through the slots b and b in the bottom of said seats 13 and B.The opposite extremity of the bracket E has formed therewith a hub, c,which is mounted on a horizontal bar, 6", and the bracket held to placethereon by means of atighteningscrew,

I desire it to'be distinctly understood that the L-shaped depending armsnot only insure certainty of position of the knives for the cleaningoperation, but also obviate tensional friction.Forexample,whilethesericsofknives are formed preferably integral witheach of the rectangular-shaped longitudinal bars from an economicalstandpoint and for operation, so that a series of knives of one barwilloccupy aposition between a series of knives of the opposite bar,yet, nevertheless, they are not so arranged and supported on the bracketas to produce a friction between them and the material undergoing thecleaning operation, because if a tensional friction were produced, thematerial, from its very nature, would be instantly severed or cut andthe device rendered incapable of performing the function and ends to beaccomplished-that is to say, removing mote, fuzz, or small particlesfrom yarn or fibrous materialin its passage between them. This I havefully demonstrated in the actual practice of the invention and havefound that excellent results are produced by forming the L-shaped armsat each extremity of the longitudinal bars A and A, which insures aproper situation of the respective series of knives from each other.

WVith special reference now to Fig. 2,which" shows a sectional sideelevation of so much of v a spoofing-machine as will serve to illustratethe manner of applying my improved cleaning device thereto, and in whichI is a portion of one of the standards of the machines, J is thebobbinholder. J is a curved arm having hinged thereto a light dependingwire guide, j, of any suitable construction and which supports thebobbin 7' and guides the yarn or other material from the bobbin andthereby regulating as well the tension of the same therefrom. Thebobbinholder J and the wire guidej are suitably hinged to a rightangularbracket, J attached to a frame, j running along the front of themachine. it is a hook-bearing secured to the lower crossframe, i, of themachine, in which is mounted a shaft, 70, carrying a rocker-arm, k,which is actuated by a heart cam movement (not shown, but which is sowell understood as to not require any further mention or illustrationthereof.) One extremity of the rockerarm in" is pivoted to a verticalconnecting-rod, l, having a slight oscillating movement, and this rod ispivoted at its upper extremity to a a collar, Z, secured to a verticalrod, m, moving freely up and down through the horizon tal arms of abracket, a, suitably attached to the machine when motion has beencommunicated to the rocker arm it, in any well-understood manner.

The brackets n at the respective ends of the machine have formedtherewith a horizcntal frame, 12 extending the width of the machine, anda frame, a, is preferably secured to each end of the standards. Atsuitable distances apart in these framesn and n are formed 0 bearings a,for the reception of the spindles O, and to each of these spindles issecured a grooved wheel, a actuated through abelt, a, passing around africtional drum, P, suitably journaled in the standards of the machine.Motion is imparted to this drum P through a belt, P, passing aroundapulley secured to a main driving-shaft. p is a spool mounted on theupper extremity of the spindle 0. To the upper extremities of thevertical rods m is suitably secured a horizontal rod, 6, on which one ormore of the hubs e" of the brackets E are fitted and held in positionthereon by means of tightening-screws c. To the seats e of each bracketare mounted the right-angular supporting-seats B and B of thelongitudinal bars A and A, each provided with a series of knives, a anda, and held to place thereon by means of the screws c.

To the horizontal rod 0 or to the bracket E, is attached ashort verticalrod, R, having a slotted upper extremity, through which the yarn orother material is guided in its passage from the bobbinj to the cleaningdevice and therefrom to the spool 12.

The vertical connecting-rod Z, actuated by the rocker-arm k imparts anup-and-down movement to the horizontal rod 0, and moving therewith thecleaning device and vertical guide R, thereby automatically laying upthe thread or yarn evenly onto the spoolwhen revolved by means of thebelt n,passing around the grooved pulley a of the spindle 0, when thefrictional drum P has had motion imparted to it from any suitablesource.

The manner of applying my improved cleaning device to a spoofing-machineof the type illustrated in the drawings having been hereinbeforedescribed, I will now explain briefly the operation thereof. I :0

The yarn or other fibrous material to be cleaned is passed in an upwarddirection from the bobbin j, held in the holder J, around the lowerportion of the wire guidej, thence over the adjustable guide D in oneend of the depending arms aand a of the longitudinal bars A and A, andbetween the two series of knives of the cleaning device, thence over theguide D, and thence upward through the slotted guide R and onto thespool p, whereon it is evenly wound when the mechanism of the machinehereinbefore described has been actuated, and all fuzz or other fineparticles readily and effectually removed during the operation.

Having thus described the nature and objects of my invention,what Iclaim as new, and desire to secure by Letters Patent, is-
